Warning Signs of Malignant Melanoma
Melanoma is the most serious and dangerous form of skin cancer. It quickly spreads to other parts of the body and can be fatal. The incidence of melanoma is increasing faster than any other type of cancer in the United States. The first sign of melanoma is often a change in the size, shape, color, or feel of an existing mole. Melanoma also can appear as a new black, blue-black, or red-bordered mole. Learn the warning signs of malignant melanoma so you can detect any changes in a mole early. Think of the letters “ABCD” to help you remember what to look for.
• A—Asymmetry. Half of the mole does not match the other half.
• B—Border. The mole’s edges are often ragged, notched, blurred, or irregular in outline. The pigment (color) may spread into the surrounding skin.
• C—Color. The color is typically uneven. Multiple colors—black, brown, tan, gray, red, pink, or blue—may be present.
• D—Diameter. The mole usually increases in size. Melanomas are typically larger than a pencil eraser (half an inch).
Melanomas vary greatly in appearance. Some have all of the above features; others may have only one or two. The most important thing to remember is to tell your doctor about any change you see in a mole as soon as possible so he or she can make a definite diagnosis. When detected and treated early, melanoma can be cured before it has a chance to grow and spread to other parts of the body.
